streaming-markdown

Streaming Markdown parser for incremental rendering of markdown as it's written, targeting AI chat-style outputs. Current version 0.2.15. Actively developed with experimental features. Ships TypeScript types. Key differentiator: optimistic parsing – immediately renders partial tokens (e.g., inline code, bold) without waiting for closing markers, supporting selectable text during streaming. The library exposes a custom Renderer interface for DOM control, with built-in default renderer and logger renderer. Minimal bundle size (~3 kB gzipped). Requires Node >=20 for server-side use.
